If a content plugin exports in ContentGetValueW a value of type ft_numeric_floating together with the trailing wide string representation of the floating-point number then button Load from file under cursor of the change attributes dialog displays a wrong value. It looks like the trailing wide string is casted to (simple) string where it should be wide string instead.

Please see my screen shots. From Image: http://tbeu.de/forum/wdx_1.png you can see that wdx returns correct numeric value and correct trailing wide string representation. In Image: http://tbeu.de/forum/wdx_2.png you see that this trailing wide string representation correctly is displayed in custom column but not in value field of change attributes dialog after clicking button Load from file under cursor.
